Boot flags
(semi-
volatile)
[1]
(continued)
5 Data 3
[7] - 1b = Lock out (power off/ sleep request) via Power Button
[6:5] - Firmware (BIOS) Verbosity (Directs what appears on POST display)
00b = System default
01b = Request quiet display
10b = Request verbose display
11b = reserved
[4] - 1b = Force progress event traps. When set to 1b, the BMC
transmits PET traps for BIOS progress events to the LAN or serial/modem
destination for the session that set the flag. Since this capability uses PET
traps, this bit is ignored if for connection modes that do not support PET
such as Basic Mode and Terminal Mode
[3] - 1b = User password bypass. When set to 1b, the managed client’s
BIOS boots the system and bypasses any user or boot password that
might be set in the system
[2] - 1b = Lock Sleep Button. When set to 1b, directs BIOS to disable the
sleep button operation for the system, normally until the next
boot cycle
[1:0] -00b = Console redirection occurs per BIOS configuration setting
01b = Suppress (skip) console redirection if enabled
10b = Request console redirection be enabled
11b = Reserved
Data 4
[7:4] - Reserved
[3] - BIOS Shared Mode Override
Can be used to request BIOS to temporarily place the channel into Shared
access mode.
Per the recommendations in the IPMI specification, ‘Shared’ access would
cause the baseboard serial controller to both remain enabled after POST/
start of OS boot, while also allowing the BMC to be accessible. This can be
useful when booting to an alternative device such as a Diagnostic Partition
since it means the partition can use the serial port but that communication
with the BMC can remain available if the partition software fails.
1b = Request BIOS to temporarily set the access mode for the
channel specified in parameter #6 to ‘Shared’. This is typically
accomplished by sending a ‘Set Channel Access’ command to set
the volatile access mode setting in the BMC
0b = No request to BIOS to change present access mode setting
[2:0] - BIOS Mux Control Override
Can be used to request BIOS to force a particular setting of the serial/
modem mux at the conclusion of POST / start of OS boot. This override
takes precedence over the mux settings for the access mode even if the
BIOS Shared Mode Override is set.
000b = BIOS uses recommended setting of the mux at the end of POST
(See IPMI specification for more info)
001b = Requests BIOS to force mux to BMC at conclusion of POST/start of
OS
-
boot. If honored, this overrides the recommended setting of the
mux at the end of POST (See IPMI specification for more info)
010b = Requests BIOS to force mux to system at conclusion of POST/start
of OS-boot. If honored, this overrides the recommended setting of
the mux at the end of POST. (See IPMI specification for more info)
Data 5 - Reserved
